Sinograce Chemical - Jingangtai rafting trip On August 17th, Sinograce Chemical Marketing Center carried out the second quarter group building activities of the Rapids Warriors, blue sky and white clouds, green mountains and green waters, riding a rubber boat, leaping in the cool water, Sometimes light as a swallow, Now and then it gallops like a tiger, the event The thrills not only make the...
Water - based acrylic emulsion formulation needs to be considered: water - based acrylic resin composition The choice of emulsion raw materials is the most important decision for engineers when formulating aqueous paint formulations.The main properties of the coating are determined by the resin.A wide variety of water-based acrylate emulsions, including polystyrene-acrylate emulsions, are on the m...
As the saying goes, three-point paint, seven-point painting. For water-based coatings, especially for water-based wood coating in the home improvement market, the level of coating technology has a direct impact on product use. In order to let everyone better master the water-based paint technology, we specially launched the water-based paint coating process series this week. The substrate treatmen...
The third step in the treatment of water-based paint coated substrates is sealing. The role of the water-based putty is to make the surface of the substrate such as wood not very regular and smooth and minor defects and defects, such as pores, fine cracks, pits, joints and concrete, to reduce the surface roughness and increase the flatness.The requirements for water-based putty are good adhesion a...
Spraying construction paint film than brush paint film more flat. Spray with water-based wood paint should be added on the basis of the original paint 5% ~ 30% of the tap water dilute after use, for the viscosity of the paint water should also increase, the diluted paint after its coating a 4 cup viscosity should be around 18 ~ 20s. Dilute mix well should be static at least 20 minutes, until the b...
Water based polyurethane resin refers to a binary colloidal system in which a polyurethane resin is dissolved or dispersed in water.Water-based polyurethane resin has the advantages of easy to use, stable performance, strong adhesion, excellent gloss, good heat resistance, etc. It can be suitable for various printing methods, especially suitable for screen printing, plastic packaging and composite...
Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...
Development trend of waterborne polyurethane: Nowadays, with the stricter requirements of environmental protection policies, the environmental protection requirements for the performance of adhesives will become higher and higher. Therefore, the greening and environmental protection of composite materials will be more and more important. There will be even more urgency.Therefore, the points mentio...
Precautions for using two-component polyurethane adhesives 1.Before applying the adhesive, the surface of the adherend must be clean, dry and free of grease. 2.The resin and curing agent should be mixed in the required ratio. 3.When scraping the glue, please try to scrape it carefully as it has a defoaming effect. 4.Store adhesive in (> 10, <50 * C) and dry place 5.Run out of the mixed glue ...
Material property (pu for short) is divided into: Pouring polyurethane elastomer (CPU for short) is one of the most widely used polyurethane elastomers with the largest yield. Thermoplastic polyurethane elastomer (TPU) -- thermoplastic polyurethane elastomer accounts for about 25% of the total amount of polyurethane.Mixed polyurethane elastomer (MPU) - accounts for about 10% of the total amount of...
Polyurethane and general epoxy products application The use of the two products requires strengthened compressive tensile cement floors or floors and drainage ditches that are resistant to corrosion by strong acids and alkalis, such as chemicals, metallurgical plants, electroplating plants, power plants, pharmaceutical plants, PCB circuit board plants, paper mills, Hardware factory, printing and d...
1.Paper-based coating resins have been switched from natural water-based resins such as celluloses to synthetic resin emulsions such as carboxystyrene butadiene emulsions, polyvinyl acetate emulsions, and acrylic emulsions, among which acrylic emulsions have more excellent properties.However, the above resins are still difficult to meet the higher requirements for the development of coated paper. ...
Glass fiber is an important reinforcing material for the manufacture of fiber reinforced plastics (FRP), and is also used for weaving high temperature resistant fiber cloth.But the glass fiber that has not been treated is brittle, easy to take static electricity after friction, and the surface is smooth, when making the reinforcing material of the resin is not easy to stick with the resin.In the m...
Environmentally friendly water-based polyurethane waterproof coating is two-component,The component A is an isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanate, and the component B is a colored liquid composed of a plasticizer, a curing agent, a thickener, a coagulant, and a filler.After use, the two components of methyl and ethyl are evenly mixed according to...
